NTCIR-15 FinNum-2 (Numeral Attachment in Financial Tweets)

Test Collection

Numeral is a crucial part of financial documents. In order to understand the detail of opinions in financial documents, we should not only analyze the text, but also need to assay the numeric information in depth. Because of the informal writing style, analyzing social media data is more challenging than analyzing news and official documents. FinNum is a task for fine-grained numeral understanding in financial social media data - to identify the linking between the target cashtag and the target numeral.
